Every police officer in the UK, every journalist (good one), anyone with an ounce of common sense who’s been following the story has it figured out (in detail).

They’ve done this by the book! They’ve had him as a suspect from early stages. The reason they didn’t release any CCTV to the public at first, or make an arrest, is because they would have had him under surveillance… hoping he could lead them to her being alive.
(Until there’s a body… it’s first and foremost an abduction investigation)

They’ve drip fed the media (and public) with information at the right time… they know exactly what their doing, and they’ve done it extremely well (hat’s off to them).

I think a shit load of people are wanting to wake tomorrow to the headline news of a confession.
